CARPET FABRIC.

SPECIFICATION forming part of Letters Patent No. 363,366, dated May 24,1887. Application filed February 19, 1886. Serial No. 192,533.(Specimens) Massachusetts, have invented an Improvement in CarpetFabrics, of which the following description, in connection with theaccompanying drawings, is a specification, likeletters 011 the drawingsrepresenting like parts.

This invention has for its object the production of a double-facedribbed carpet fabric, either side of which may be used uppermost, bothfaces exhibiting a pattern showing warpthreads of three or more colors.

My improved carpet fabric is composed of figuring-warps, binder-warps,and stuffer and binder wefts, the stuffer-weft larger than thebinder-weft, and cooperating with the figur-- ing-warps, serving to givethe fabric a ribbed appearance, like a pile fabric. I

Myinvention consists in a carpet fabric composed of three or more setsof figuring-warps, aset of binder-warps, and stuffer and binder weft,two sets of the figuring-warps appearing on the two faces of the fabricto form each of the ribs, such sets being formed from portions of threeor more sets of warpthreads, the threads of that set of warps which donot appear at one or the other face of the fabric when the staffer-warpis being inserted being retained at the center of the fabric between thestuffer-weft of the opposite sides, so as to 0011- stitute a body forthe fabric.

Figure l is a longitudinal section, on an en larged scale, of acarpetfabric embodying my invention, and Fig. 2 a plan view of a part of thecarpet with the warp and weft spread out to show their crossing.

My improved carpet fabric consists, essentially, of three or more setsof figuring-warps, a b c, a binder-warp, d, a staffer-weft, c, and abinder-weft, f. Each set of warps a b 0 may be of a separate color, orbe party-colored, or be striped in the chain.

' To produce my improved fabric I may make use of any ordinarytwo-shuttle Jacquard loom, well known in the art to which my inventionrelates, it having usual harness or cords to receive the figuring-warps,and usual means such as a comber-board or griffsto raise and lower theharness or cords in proper order or sequence, in accordance with thedemands of the patterncards carried by the usual patterncylinder.

One jacquard which may be employed to advantage in the manipulation ofthe figuringwarps in the production of my improved carpet fabric isdescribed in United States Patent No. 230,591, dated July 27, 1880.

To move the binder-warp I prefer to our ploy a harnessframe having usualheddles, the said harness-frame being operated through any of thewell-known instrumentalities deriving their movement from, say, a cam onthe picker-shaft.

By means of the jacquard either of the said figuring-warps may be madeto appear at either face or side of the carpet, as desired, preparatoryto inserting the staffer-weft c. The binderwarp will preferably becontrolled by one harnessframe.

The binder-warp will pass from one to the other face or side of thefabric, and be there locked by a shot of binder-weft, f. Herein I haveshown two picks of stuffer-weft as followed by two picks of binder-weft.

Referring to the left-hand end of Fig. 1, the figuring-warp a is shownas exposed at the upper side of the fabric for two picks of thestutter-weft. Then the said Warp is thrown to the under side of thefabric for one-pick of the stuffer-weft, and thereafter for two picks ofthe stuffer-weft, taking into consideration but one side of the fabric,the said warp remaining concealed in the fabric, appearing again,however, at the upper side of the fabric. for, as herein shown, threepicks.

The figuring-warp 1), commencing at theleft of Fig. 1, is down at theunder side of the fab-- ric for two picks of the staffer-weft at thatside, then remains in the fabric for one pick of staffer-weft at eachside of the fabric, and then passes to the upper side of the fabric,where it remains for one pick of staffer-weft, and then passes to theunder side of the fabric for another pick of stuffer-weft, andthereafter, as herein sl1ow11,-the warp 6 remains concealed in thefabric and does not appear at either side thereof.

The figuring-warp 0, commencing at the left of 1, is concealed whilethree picks of of the fabric, and then the said warp is brought.

stuffer-weft are introduced at the upper side to the upper side of thefabric for one pick of stutter-weft at that side, and then the said Warpis carried to the under side of the said fabric for three picks of thestuffer-weft at that side, when the said warp is again carried into thecenter of the fabric and concealed.

The binder-warp is made to appear uniformly first at the under and thenat the upper side of the fabric, and the said warp is caught and held bythe binder-weft, the said binder warp and weft completing the integrityof the fabric, and being the only threads that are interlockeduniformly.

By inspecting the drawings it will be seen that either one'of the threesets of figuring- Warps may be made to appear at either side of thefabric for one or more picks of stufferweft, or be concealed in thecenter of the fabric, and with three sets of figuringwarpaeachcontrolled by usual Jacquard harness, it is possible to make a fabric inwhich three colors may be made to appear in pattern at every pick ofstaffer-Weft at both the upper and under side of the fabric, it beingassumed that all the warps of each set are of the same color.

If each set of figuring-warps were held by one harness-frame of anyordinary fancy loom, and all the warps of one color be moved together,then all the threads raised or lowered for any one pick of staffer-weftwould be of vention to leaving any particular warp-thread up or down forany particular number of picks, as that will depend upon the patternbeing woven or produced by the warps of different color.

The essential feature of my invention is that some of the threads of anyset may be made to appear and to figure the upper and the lower side ofthe fabric at any pick.

It is obvious that I'may employ more than three sets of warps in properJacquard harness, and gain in the number of colors that may be made toappear in the carpet to produce the pattern.

I claim-- The hereindescribed carpet fabric, composed of three or moresets of figuring-warps, one single set of binder-warp, and a stutter anda binder weft, two of said sets of figuringwarps being made to appear atintervals at both the upper and under sides of the said fabric, the setor sets of figuring-warps not appearing at either surface of the fabricfor one or more picks being buried in the body of the fabric, bothsurfaces of the fabric presenting ribs formed by the loops ofwarp-thread filled by the stuffer weft, all substantially as described.

In testimony whereof I have signedmy name to this specification in thepresence of two subscribing witnesses.

GEO. CROMPTON.
